Howard Leight™ TrustFit® Plus reusable push-in earplugs are designed with an ergonomic stem and dimpled foam tip so they are easy to fully insert and remove without picking up dirt from workers' fingers and comfortable to wear during the workday. A flared end on bell-shaped earplugs provides extra material to cover the outside of the ear canal to help block sound. The extra material also provides a gripping point to aid insertion and removal of the plug. Corded/Cordless Pair: Cordless; Shape: Bell; Material(s): Foam; Noise Reduction Rate (NRR): 31 dB.
